The present work describes the synthesis of nitrogen doped multi-walled carbon nanotubes (CNx CNT). The chosen production method was the catalytic pyrolysis of a solid mixture containing [Ni(DMG)2] and melamine (C3H6N6), under an Αr atmosphere. A series of various experiments were performed, using different proportions of the reaction mixture, in order to optimize the production conditions of nitrogen doped carbon nanotubes. Finally, the produced materials were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), Raman spectroscopy as well as thermogravimetric analysis (TGA). The obtained data from all the above analyses, showed the formation of nitrogen doped carbon nanotubes of various diameters as well as nanofibers surrounded by byproducts such as aggregations of amorphous carbon and metallic catalyst, depending on the proportion of the reaction mixture.

The time characteristics of resistance change of individual nitrogen-doped multi-walled carbon nanotubes (N-MWCNTs), initial and irradiated with electrons, protons and argon ions has been measured upon exposure to ammonia and nitrogen dioxide. It is found that the initial N-MWCNTs have n-type conductivity, N-MWCNTs irradiated with protons and argon ions have p-type conductivity, and those irradiated with electrons have n-type conductivity. The relative gas sensitivity of individual N-MWCNTs, initial and irradiated with ions and electrons, has been determined
